A famous elderly Australian entertainer arrested and questioned by Scotland Yard detectives in London on suspicion of sexual offences has still not been named.

The high-profile Australian, aged 82, who now lives in Berkshire, south east England, was interviewed for several hours by police before being released on bail about 11.30pm local time, Australian media are reporting.

It is understood his lawyer was present.

British media have not named the man for legal reasons, while Australian mainstream media have also withheld the man's name at this stage.

The man is the 11th suspect arrested under Operation Yewtree, which was set up last year to probe hundreds of claims of sexual assault and paedophilia against British entertainer Jimmy Savile.

Berkshire police have confirmed the arrest is not directly linked to Savile.

A Metropolitan Police spokesman said the man had been bailed, pending further inquiries, to appear before police again in May.

"In a general sense I can say we are only likely to confirm something like that after it takes place," he said, adding security of witnesses was paramount.

The Guardian newspaper has reported the man's London-based agent could not be contacted while his manager and brother also refused to talk about the arrest.

Asked if he had anything to say on his younger brother's behalf, the man said: "No I haven't, thank you.''

Late last year a friend of the Australian married father said his mate was "almost suicidal" over his being interviewed by police for alleged sexual offences which he described as being a slur and based only on guilt by association since he knew Savile, who has since been branded one of Britain's worst serial child sexual abusers with up to 450 victims as young as nine years old over a five decade period.

They have all denied any wrongdoing, except for Glitter, who has not made a statement.

Police this week told BBC producer Wilfrid De'ath he was no longer facing charges after a woman who initially claimed he groped her withdrew her complaint. He is the only suspect where the Crown Prosecution Service has made a decision on.
